an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Dual Linearly Polarized Microstrip Array Antenna

Recently, Multiple Input Multiple Output (MIMO) has become popular research topic among researchers for development of a new wireless communications technology. The system capacity can be increase with deployment of MIMO technique in the communications system. Thus, the used of high frequency bandwidth can be avoid since this method required high cost implementation. High transmitted power also...

Microstrip Antenna Array with I-Shaped DGS

This paper proposed a microstrip antenna array with DGS (Defective Ground Structure). The structure in this work is 2*1 microstrip patch array antenna using substrate with h= 0.762 mm and εr = 3.2. Two triangular-shaped patches are located on opposite side of PCB and spaced 14mm apart by a small ground portion. The proposed DGS of I-shape is placed in the ground plane. It does provide a method ...

Analysis of Metamaterial Based Microstrip Array Antenna

Microstrip Antenna Array for Beamforming Systems

A dual and quad element antenna array resonating at 2.4 GHz with narrow beam is proposed in this paper. An intention to put forward this work is to make use of microstrip patch antennas in beamforming to form directional beams in analog and digital domains; reducing co-channel / multipath interferences and improving Quality of Service (QoS) for senor arrays and 3G wireless networks. The size of...
